It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

In this context, it is to be understood that the terms involved:

FunView: is a cross-platform view control with dynamic analysis rendering capability;

XmlNode: is the view node structure in FunView that is used to describe the user interface style.

The message card generation method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The data storage system may store data that the server 104 needs to process. The data storage system may be integrated on the server 104 or may be located on the cloud or other servers. When a worker on the server 104 side needs to push a message card to the terminal 102 side, a message card generation request containing template specification information and service data can be sent to the terminal 102, and the terminal 102 obtains the message card generation request containing the template specification information and the service data; obtaining a message template corresponding to the message card generation request based on the template specification information; obtaining message data according to the message template and the service data; identifying expression data in the message data, searching instruction data corresponding to the expression data in an expression instruction set, obtaining an operation result of the expression data according to the instruction data, generating the instruction data in the expression instruction set based on nodes in abstract syntax trees of various expressions in traversal history data, constructing the abstract syntax trees by performing lexical analysis and grammar analysis on various expressions in the history data, and representing operands or operators of the expression algorithm by the nodes in the abstract syntax trees; and finally, rendering and generating a message card on a display screen of the terminal 102 based on the message data and the operation result. The terminals 102 and 104 may be, but not limited to, various desktop computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.

In one embodiment, as shown in fig. 2, a message card generating method is provided, and the method is applied to the terminal 102 in fig. 1 for illustration, and includes the following steps:

step 201, a message card generation request containing template specification information and service data is acquired.

Where a message card generation request refers to a request that the server 104 wishes to generate by communicating information through the message card. The message card is also called card message, which is a structured message that can provide an easy-to-use, unified rich interactive form. In one embodiment, the message card may specifically refer to a FunView message, where FunView is a cross-platform view control with dynamic parsing and rendering capability, and is widely used in message flows of various instant messaging software at present, and the FunView performs dynamic parsing and rendering based on templates and data, where the templates are a pattern description set, and are issued with the message in a file link form, dynamically downloaded and parsed when needed, and then combined with data operation to obtain a renderable view tree, and finally drawn on a screen. The message card generation request specifically comprises template specification information and service data, wherein the template specification information is used for specifying a message template used in the message card generation process, and the service data is also used for filling the message template to obtain data of the message card. The template specification information is used for specifying a message template used for generating the message card, and the template specification information can specifically specify a required message template through information such as a template name, a template number or a template type.

Specifically, when the staff on the server 104 side needs to send a message to the user on the terminal 102 side, the message may be sent in the form of a message card, and at this time, the server 104 needs to submit a corresponding message card generation request to the terminal 102 first to render and generate the message card on the display interface of the terminal 102. Meanwhile, a template designating message is added to the message card generating request to designate a message template for the message card, and corresponding service data is added at the same time, after receiving the message card generating request, the server 104 may determine the template for generating the message card, and download corresponding message data from the terminal 102 side to generate the message card. In one embodiment, the scheme of the application is suitable for instant messaging software used for enterprise internal communication, the message card can be specifically a FunView message, when enterprise personnel need to send the message to individual users or group chat in the instant messaging software, the data can be sent in the form of the FunView message card, at the moment, the message card generation request needs to be submitted to each terminal, meanwhile, template specification information and service data are submitted, the terminal 102 obtains the message data, the message template is dynamically downloaded, and then a renderable view tree is obtained through operations such as data analysis, data operation and the like, and finally, the renderable view tree is drawn on a screen of the terminal.

And 203, obtaining a message template corresponding to the message card generation request based on the template specification information.

The message template is one of the components of the message card, and the final required message card can be generated through loading and analyzing the business data and the message template. The message template specifically comprises information such as template name, template type, template content and the like. The template content comprises a specific style of the message card, and comprises a message title, a message content and the like. The final required message card (containing some of the content requiring expression calculation) can be generated by combining the business data with the message template. And the service data is data containing specific message contents. The message templates may be transmitted to the server 104 in the form of binary data.

Specifically, after the server obtains the message card generation request, the template specification information and the service data contained in the message card generation request can be resolved first, and the message card generation request is searched and downloaded to the corresponding message template according to the template specification information. Meanwhile, the binary message data can be downloaded from the terminal 102 based on the message card generation request, and then the required message card can be generated based on the message data and the message template. In one embodiment, the scheme of the application is suitable for instant messaging software used for enterprise internal communication, a plurality of message templates are preset in the instant messaging software, a terminal can specify a required message template through a template name, a server can search and download a corresponding message template through the template name when receiving a message card generation request of the terminal, and meanwhile, a terminal side can obtain service data from the message card generation request so as to generate the required message card.

And step 205, obtaining message data according to the message template and the service data.

The message data specifically refers to data obtained by combining the message template with service data after the message template is converted into a style description tree.

Specifically, the message template is specifically binary data, and needs to be rendered onto the screen of the terminal 102 through parsing processing. The parsing and rendering process of the message template specifically comprises steps of reading binary, parsing the binary into a style description tree, parsing the same data operation, converting the same style description tree into a rendering tree, and the like. The binary message template is first downloaded and read from the server 104, and then converted into a style description tree, in which the service data is combined with the intermediate nodes of the style description tree obtained by parsing the message template. The attribute node value in the template may be an expression, and the expression designates a field in the service data to be taken for operation, and at this time, after the style description tree is obtained, the corresponding field of the service data may be added to the style description tree to fill the expression therein. In one embodiment, the application is specifically used for realizing the analysis and rendering of the FunView dynamic message card, the style description tree is specifically an Xmlnode style description tree, and the service data is combined with the Xmlnode style description tree corresponding to the message template to obtain the message data.

Step 207, identifying the expression data in the message data, searching the instruction data corresponding to the expression data in the expression instruction set, obtaining the operation result of the expression data according to the instruction data, generating the instruction data in the expression instruction set based on nodes in abstract syntax trees of various expressions in the traversal history data, wherein the abstract syntax trees are constructed by performing lexical analysis and grammar analysis on various expressions in the history data, and the nodes in the abstract syntax trees represent operands or operators of the expression algorithm.

Wherein the expression is a combination obtained by a meaningful arrangement method of numbers, operators, numerical grouping symbols (brackets), free variables, constraint variables, and the like to obtain numerical values. Constraint variables have been assigned values in an expression, while free variables may be assigned values outside of the expression. Instruction data contains a plurality of instructions, and the instructions (instruction) are used for telling a computer to perform a code of a special operation. Such as: data transfer instructions, arithmetic operation instructions, bit operation instructions, program flow control instructions, string operation instructions, processor control instructions and the like, and the instructions are used for caching operation results of lexical analysis and grammar analysis in the expression operation process. Specifically, a corresponding abstract syntax tree can be generated according to the lexical analysis of the expression and the operation result of the syntax analysis, and each instruction can be generated according to node generation by traversing the abstract syntax tree. And the expression instruction set refers to an instruction set constructed based on expression data previously parsed. Nodes in the abstract syntax tree represent operands or operators of the expression algorithm. The nodes of the abstract syntax tree specifically comprise two types of leaf nodes and non-leaf nodes, the leaf nodes represent operands in one algorithm, and the non-leaf nodes represent operators in one algorithm.

Specifically, the rich and dynamic style presentation of the message card is declared by the expression together with the business data. In an actual message card business scenario, a large number of similar or repeated expressions need to be operated, and these expressions need to be subjected to repeated processes such as lexical analysis, grammar analysis, numerical operation and the like one by one, which occupy a large part of overhead in the message card analysis process. At present, the result of lexical analysis of the expression is directly cached, and when repeated expressions are encountered, the cost of repeatedly performing lexical analysis can be saved. The specific method is that the hash value of the expression is used as a key, the data structure of the lexical analysis result is used as a value, and in the lexical analysis flow, the buffer memory is updated and taken by the key value, and the specific method can be shown by referring to fig. 3, however, the method can only save the cost of the lexical analysis flow, and most of lexical analysis is performed in a sequential traversal and fresh backtracking scene, compared with the syntax analysis, the lexical analysis only accounts for about 10% of the total cost, and the cost is far less than that of the syntax analysis flow. The method brings about poor performance, so that the application provides an idea of an intermediate instruction layer, thereby effectively caching the results of lexical analysis and grammar analysis, and greatly saving the repeated expenditure when facing repeated expressions. The whole flow is changed into: the method comprises 4 steps of lexical analysis, grammar analysis, instruction generation and instruction operation, and is shown in fig. 4. Firstly, after the repeated expression is obtained, instruction data corresponding to the expression data can be directly extracted from constructed instruction data, then data operation is carried out according to the instruction data, an operation result of the expression data is obtained, and the quick operation of the expression can be directly realized through the instruction by caching lexical analysis and grammar analysis as instructions, so that the generation efficiency of a message card is improved, and the communication efficiency based on the message card is further improved.

Step 209, rendering and generating a message card based on the message data and the operation result.

Specifically, after the operation result is obtained, the style description tree corresponding to the operation result and the style description tree of the non-expression part message data may be converted into a rendering tree, and then the rendering and screen-loading processes are performed on the obtained rendering tree, so that a corresponding message card is generated on the terminal 104 side, and the generation flow of the message card is completed. In one embodiment, the scheme of the application is suitable for instant messaging software used for communication in an enterprise, and the message card can be pushed to individuals or group chat in the enterprise. When pushing to the group chat, pushing to all members in the group chat, and displaying the message card on the terminals of the members of the group chat.

The message card generation method comprises the steps of obtaining a message card generation request containing template specification information and service data; firstly, obtaining a message template corresponding to a message card generation request based on template specification information; obtaining message data according to the message template and the service data; and then, identifying the expression data in the message data, searching instruction data corresponding to the expression data in an expression instruction set, and obtaining an operation result of the expression data according to the instruction data, wherein the instruction in the expression instruction set is generated based on nodes in abstract syntax trees of various expressions in the traversal history data, and the abstract syntax trees are constructed by performing lexical analysis and syntax analysis on the various expressions in the history data, and the nodes in the abstract syntax trees represent operands or operators of the expression algorithm. By abstracting the lexical analysis and grammar analysis processes in the expression operation process into instruction data, the expression operation can be directly realized through the instruction data when repeated expressions are faced, the expenditure of the expression operation process is reduced, and finally, a message card can be rendered and generated based on the message data and the operation result.

In one embodiment, step 203 comprises: when the template loading task corresponding to the template designating information is not found in the task queue, according to the template loading task corresponding to the template designating information, registering a interception task in the created template loading task, wherein the interception task is used for intercepting the downloading completion condition of the message template designated by the template designating information; and obtaining a message template corresponding to the message card generation request based on the template loading task.

The task queues refer to queues used for sending messages, and each queue is used for realizing a task generated by a message card. The template loading task is a task of downloading a message template corresponding to a message card generation request from a template library, and because template data and business data are needed for generating the message card, the corresponding template is needed to be loaded from the template library to construct the message card when the message card needs to be generated. The interception task is a task for intercepting whether the downloading of the message template is completed or not, the downloading process of the message template can be intercepted through the interception task, and the corresponding message template can be directly obtained to execute the process of generating the follow-up message card as long as the downloading is completed.

Specifically, in the current message template using method, when a plurality of messages using the same template are required to be loaded simultaneously, each message can independently carry out the template file downloading and reading operation, and the condition that one template is read for multiple times is existed, so that unnecessary waste is caused. Therefore, as shown in fig. 5, the template loading process is managed by adding the template manager, and when the template loading action occurs, a template loading task corresponding to the template to be loaded is generated through the template manager. When a new template needs to be loaded, whether a template loading task corresponding to the new template exists or not is searched in a task queue before loading. If the message template is not stored, the template needs to be taken out through a new template loading task, at the moment, the template loading task can be established according to the message template, and a interception task is registered in the established template loading task according to the template specification information, so that the downloading flow of the message template corresponding to the template specification information is intercepted, and then the corresponding message template can be obtained through the template loading task. In the process, other template loading tasks can also determine the loading flow of the message template by monitoring the template loading tasks, so that the template reading tasks of a plurality of message card creation processes can be realized through one template loading task. In one embodiment, the scheme of the application is suitable for instant messaging software used for enterprise internal communication, at this time, a message template library can be established according to enterprise needs, different message templates are stored in the message template library by using template names as key values, when a message card needs to be established, the corresponding message template can be searched and downloaded in the message template library by using the template names, meanwhile, in the process of template loading, if other message card generating tasks need to read the message template, a process of interception for intercepting the message template loading can be directly added, and after the message template loading is completed, the generating tasks of the message cards can directly obtain the message templates for subsequent analysis and rendering processing. In this embodiment, interception and management of the template loading process are implemented through the template manager and the task queue, so that the number of times of reading the same message template can be reduced, and the processing efficiency of the process of generating the message card based on the message template is improved.

In one embodiment, step 203 further comprises: when a template loading task corresponding to the template designating information is found in the task queue, registering a interception task in the template loading task corresponding to the template designating information, wherein the interception task is used for intercepting the downloading completion condition of the message template designated by the template designating information; and when the completion of the downloading of the message template is detected based on the interception task, obtaining the message template corresponding to the message card generation request.

Specifically, as shown in fig. 6, when a new template needs to be loaded, before creating a template loading task, the server 104 searches for whether a template loading task corresponding to the new template exists in the task queue based on the template specifying information. If the message template exists, the downloading flow of the message template in the template loading task can be directly intercepted through registering the interception task, so that the template reading task of the multiple message card creation processes can be realized through one template loading task. And if the task is completed, informing all listeners that the file loading is completed, and then carrying out the next operation. And when not present, the template loading process needs to be implemented by first creating a template loading task. In this embodiment, interception and management of the template loading process are implemented through the template manager and the task queue, so that the number of times of reading the same message template can be reduced, and the processing efficiency of the process of generating the message card based on the message template is improved.

In one embodiment, step 205 comprises: analyzing the message template to obtain a style description tree; and obtaining message data according to the style description tree and the service data.

The parsing of the message template refers to parsing the message template into a style description tree. The expression data refers to part of data in the message data, after the server obtains the message template, the message template in a binary form can be converted into a corresponding data structure and then is analyzed into a style description tree, the style description tree comprises a hierarchical structure among multiple nodes, attribute description of a single node and the like, however, some attributes in the description tree at this time can be expressions and cannot be directly rendered, the data needs to be applied to the expressions, specific values are calculated and assigned to node attributes, and then the rendering tree obtained after the specific values are assigned, so that the rendering can be performed. Thus, after the style description tree is obtained, the style description tree may be combined with the business data to populate the related expressions to obtain the message data.

Specifically, after obtaining the service data and the message template, the message template needs to be converted into a style description tree, data operation, the style description tree is converted into a rendering tree, and the screen is rendered through analyzing the message template. The data operation process specifically refers to performing data operation processing on the style description tree corresponding to the expression, so as to calculate a specific value and assign the specific value to the node attribute, so that subsequent rendering processing can be performed. Therefore, after obtaining the message template, the server may parse the message template and then combine it with the service data to obtain the message data including the expression data, so as to pad for subsequent operation processing.

In one embodiment, after step 209, further comprises: acquiring a template multiplexing request containing a template identifier; searching a cache file based on the template identification, wherein the cache file comprises at least one of view cache, node cache or file cache; when the view cache corresponding to the template identifier is found, a rendering tree corresponding to the template multiplexing request is obtained through data operation processing; when the node cache corresponding to the template identifier is found, a rendering tree corresponding to the template multiplexing request is obtained through node analysis processing and data operation processing; when the file cache corresponding to the template identification is found, a rendering tree corresponding to the template multiplexing request is obtained through the template full-quantity analysis processing; when view cache, node cache and file cache corresponding to the template identification are not searched, a rendering tree corresponding to the template multiplexing request is obtained through template loading processing and template full-quantity analysis processing; and generating a message card corresponding to the template multiplexing request based on rendering of the rendering tree.

Wherein the template identification refers to identification information for identifying a desired target message template from a message template library. The template identification may specifically include a template type, a template number, a template name, and the like. The template cache file refers to a cache file of a message template, and the same template can be loaded and analyzed according to different stages to generate three products: files, style description trees, rendering view trees. The cache data of different stages are different, and unnecessary analysis processes for the message template can be reduced by identifying the cache file of the message template. And the generation efficiency of the message card is improved. The message template is a view file, so that the process of analyzing the template is also a process of analyzing the view, and the complete process of analyzing the message template also comprises the processes of loading the message template file, converting node analysis into a style description tree, operating data and the like. The view cache file contains a view tree converted from a style description tree, namely, the view cache file is generated after the message template node is resolved, so that when the view cache exists in the cache file, the current message template is indicated to have passed the template loading processing and the node resolving processing, the view tree in the template is converted into the view tree, the message template file with complete resolution can be obtained only by carrying out data operation processing on the basis of the view tree, and the specific data can be calculated by the expression in the view tree and then be endowed with attributes for rendering. The node caches the cache data corresponding to the style description tree file, and after the message template is read, the cache data can be converted into the style description tree, and the obtained cache data is the node cache file. The node cache file needs to be converted into a view tree through node analysis processing, and then the rendering tree can be obtained through data operation processing, so that the node cache is obtained, and further the analysis is performed through two steps of node analysis and data operation processing. The file caching refers to the caching of the template file, and the full-quantity analysis processing of the template comprises all analysis processes of node analysis, transformation into a style description tree, data operation and the like. If the file cache exists in the cache and the view cache and the node cache do not exist, the method indicates that the full-quantity analysis processing of the template needs to be completed once. If the file cache does not exist, the message template is read first, and then the template full-quantity analysis processing is carried out, so that the rendering tree for rendering can be obtained.

Specifically, the application can also realize the multiplexing of the message templates through the template cache file, and can realize the searching of the message template related cache data or the message template body by the template identification of the message templates and then taking the template identification as a key value. Because three different products, namely three products of a file, a style description tree and a rendering view tree are generated in the template process, and template cache files corresponding to the different products can be searched by setting a multi-level cache mechanism, then different template loading processes are carried out based on the searched cache files, and the analysis process for the message template is reduced, so that the processing efficiency is ensured. In one embodiment, as shown in fig. 7, when the view cache file obtained by final parsing is found, only the rendering tree corresponding to the template multiplexing request needs to be obtained through data operation processing. When only the Xmlnode cache file of the node cache is found, the Xmlnode cache file is required to be converted into a view tree through Xmlnode analysis, and then the rendering is obtained through data operation processing. When only the file cache corresponding to the template identifier is found, the rendering tree corresponding to the template multiplexing request can be obtained by executing the template full-quantity analysis processing comprising style description tree conversion, node analysis and data operation on the message template file, and if the file cache is not found, the corresponding message template file is loaded first and then the template full-quantity analysis is carried out. In this embodiment, the template cache file is searched through the template identifier, so that loading analysis of the message template can be performed through the template cache file, the analysis flow of the message template is reduced, and the generation efficiency of the message card is improved.

In one embodiment, before step 207, further comprises: acquiring expression data in historical data; performing lexical analysis processing on the expression data in the historical data to obtain word stream data; carrying out grammar analysis processing on word stream data to construct an abstract grammar tree; traversing each node in the abstract syntax tree, and generating each instruction in the instruction data according to the traversing result.

The term analysis refers to a process of converting a character sequence into a word (Token) stream in computer science. The program or function that performs the lexical analysis is called a lexical analyzer, also called a scanner. The lexical analyzer typically exists in the form of a function for the parser to call. The program that performs the lexical analysis task is called a lexical analysis program or a lexical analyzer or scanner. The program that performs the lexical analysis task is called a lexical analysis program or a lexical analyzer or scanner. The source program is scanned from left to right, various words are identified according to the lexical rules of the language, and attribute words of the corresponding words are generated. Whereas parsing is a logical stage of the compilation process. The task of parsing is to combine word sequences into various grammar phrases such as "programs", "sentences", "expressions", etc., on the basis of lexical analysis. The parser determines if the source program is structurally correct. The structure of the source program is described by context-free grammar. The parser may also be automatically generated with tools. The process of completing a parser task is called a parser, or parser. And identifying corresponding grammar category from the lexical analysis result according to grammar rules of the source language, and simultaneously carrying out grammar checking. An abstract Syntax tree (Abstract Syntax Tree, AST), or simply Syntax tree (syncax tree), is an abstract representation of the source code Syntax structure. It represents the syntax structure of a programming language in the form of a tree, each node on the tree representing a structure in the source code. The scheme of the application is mainly used for processing the expression data. Thus, a node characterizes an operand or operator of an expression algorithm. And generating each instruction in the instruction data according to the traversing result by traversing each node in the abstract syntax tree.

Specifically, the scheme of the application analyzes and caches the lexical analysis and grammar analysis processes through instruction data to obtain each instruction data, and the instructions can be specifically generated through grammar analysis. Firstly, lexical analysis is needed to be carried out on each expression in the historical data through a lexical analyzer such as a Lex and the like to obtain word stream data corresponding to the expression, then the word stream data is subjected to syntax analysis through a syntax analyzer such as a Yacc and the like, so that a corresponding abstract syntax tree is constructed, and after the syntax analysis tree is obtained, instructions corresponding to each node can be obtained through traversing the nodes. In one embodiment, the process of constructing each instruction in the instruction data based on the expression "a=b+c×d" in the history data may be shown in fig. 8, where the expression is firstly lexically analyzed by the lexical analysis tool Lex to obtain word stream data "id1=id2+id3-id4", then the word stream is parsed by the syntax analysis tool Yace to obtain an abstract syntax tree as shown in the figure, and then the nodes in the abstract syntax tree are traversed, where the found instruction includes "load id3", "mulid 4", "add id2" and "store id1"4 instructions. In this embodiment, various instructions can be constructed by analyzing the grammar of the expression, and the instruction data can be directly used for operation during the subsequent data operation processing, so that the generation efficiency of the message card is improved.

In one embodiment, the operation result of obtaining the expression data according to the instruction data includes: performing field nulling processing on the instruction data, and identifying data to be optimized in the instruction data; optimizing the instruction data based on the data to be optimized to obtain an optimized instruction; and obtaining an operation result of the expression data according to the optimization instruction.

The optimizing processing of the instruction specifically refers to optimizing a part of empty judgment instructions in the instruction data, for example, the grammar of common array empty judgment (array capacity) and the grammar of character string empty judgment (character string length) can be optimized, so that a plurality of instructions are replaced by a single instruction.

Specifically, the found instructions may include partial null instructions, and in order to reduce the consumption of instruction execution, the null instructions may be optimized first. At this time, whether each instruction in the instruction data is a null instruction or not can be identified through a null instruction (check_empty), and null operation is specially executed through the null instruction, so that null can be performed on an array and a character string in the instruction data, and the previous LOAD, CALL, EQAL three instructions can be replaced. Therefore, the instruction quantity is reduced, and the processing efficiency of the data operation process is improved. In one embodiment, as shown in the left side of fig. 9, the data to be optimized is first identified from the code of the instruction data, where two "desc_list.size ()" and "num 0" are included. Therefore, the first three instructions in the right side of fig. 9 are optimized, and the found instruction corresponding to the EMPTY judging operation is replaced by the check_empty instruction. In this embodiment, the number of instructions can be effectively reduced by the void determination processing of the instruction data, thereby improving the processing efficiency in the data operation processing process.

In one embodiment, the operation result of obtaining the expression data according to the instruction data includes: identifying a highest frequency data field in the instruction data; constructing a quick access instruction corresponding to the highest frequency data field; updating instruction data based on the quick access instruction; and obtaining the operation result of the expression data through the updated instruction data.

The highest frequency data field refers to a data field with highest occurrence frequency in the instruction data containing all instructions. Such more frequently occurring data fields generally need to be accessed by a policy that progressively accesses nested fields. The quick access instruction is a strategy capable of accessing the nested fields at one time, and can prevent the data from being repeatedly circulated in the temporary register.

Specifically, the scheme of the application can also simplify the data operation processing process through field access optimization measures, and identify the highest frequency data field in the instruction data; constructing a quick access instruction corresponding to the highest frequency data field; updating instruction data based on the quick access instruction; and obtaining the direct access grammar of the expression data aiming at the highest frequency data field by the operation result of the updated instruction data, and replacing the strategy of accessing the nested fields step by step with the strategy of accessing the nested fields once, thereby avoiding repeated circulation of the data in the temporary register. For the highest frequency data field, the highest frequency data field can be converted into a one-time access nested field, so that the optimization of instruction data is realized. In this embodiment, the flow of the data operation can be effectively simplified through field access optimization, so as to improve the processing efficiency of the data operation.

In one embodiment, the operation result of obtaining the expression data according to the instruction data includes: recognizing constant expression nodes in expression data, wherein the constant expression is a grammar node with constant operands; performing data operation processing on the constant expression nodes to obtain constant operation results; replacing constant expression nodes in the expression data with constant operation results corresponding to the constant expression nodes to update the expression data; and searching instruction data corresponding to the updated expression data in the expression instruction set, and obtaining an operation result of the expression data according to the instruction data.

The constant expression is a grammar node with constant operands, and the grammar node can directly calculate to obtain a result to replace the original node.

Specifically, the application can also optimize the constant expression in the expression data, if all operands in one node of the expression are identified as constants, as shown in fig. 10, wherein the operands in the node (2+1) are constants, so that the constant operation result is obtained by firstly operating the constant expression, then replacing the original (2+1) with 3 to update the expression, and then acquiring instruction data according to the updated expression, thereby directly avoiding generating instructions and improving the processing efficiency of the data operation process. In this embodiment, the constant expression optimization is used to further optimize the expression data, so that the processing efficiency can be effectively improved.

At this time, for the loading process of the message template, the template loading task corresponding to the template designating information can be searched in the task queue for loading the message template based on the template designating message, when the template loading task corresponding to the template designating information is not searched in the task queue, the interception task is registered in the created template loading task according to the template loading task corresponding to the template designating information, and the interception task is used for intercepting the downloading completion condition of the message template designated by the template designating information; and obtaining a message template corresponding to the message card generation request based on the template loading task.
